I dont understand why two handed forehand is not treated as slice. We choose topspin backhand or slice when it is more effective. Why couldnt we choose between one handed and two handed forehand ? Two handed forehand is more effective inside the court when we dont have time for full swing. We can hit the ball on the rise and create great angles. One handed forehand is better when the ball is far from us or when we are far behind the baseline. Would you be worse player if additionally you could play two handed forehand ?
